TRACTOR AND IMPLEMENT CONSTRUCTION.

Continuation ot application Serial 11o. 245,205, iiled July 16, 1918. This application tiled July 29, 1925.

Serial No. 46,776.

The present application is a continuation of an application filed by me July 16, 1918, Serial No. 245,205.

This invention has for its object a tractor and implement construction by which a machine having power driven mechanism as for instance, a mower having a mower knife, a binder etc. may be drawn by the tractor, and the mechanism thereof actuated b the power plant of the tractor instead of eing actuated from the ground wheels of such machine. The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a longitudinal sectional v1ew of a preferable form of my tractor.

Fig.` 2 is an enlarged detail view of the driven member which actuates the movable parts .of the machine being drawn by the tractor.,

This l tractor comprises generally, two driven elements independent of each other, a tractor Wheel connected to one of said driven elements, the other of the driven elements being adapted to be connected to the movable parts of the machine being drawn by the tractor, a motor, power transmitting connections between the motor and the driven elements, the power transmitting connections preferably including a member common to or connected to both of said driven elements and also change speed gearing4 between the motor and said member so that both driven elements although independent of each other and driving different sets of mechanism are alike subject to the different s eed changes.

I have gere shown my invention as cmbodied in the Ford tractor in which .the frame comprises a casting 1 for the earmg, and the engine base 2, the parts 1 an 2 supporting the axles for the front wheels 3 and the rear tractor or ground wheels 4, the latter being connected to a driven element comprising a differential gear 5 and the shaft sections, as the section 6, connected to the differential gearing and to the tractor wheels respectively.

7 is `the second driven element which 1s here shown as a shaft journaled in a bearing 8 formed inthe cover plate 9 secured to the rear end of the casing 1, the rear end of the shaft 7 being coupled by any suitable means as a universal joint 10 to a shaft 11 adapted to be connected to the mechanism of the machine being drawn, as a mower knife or other movable mechanism of any other agricultural machine which is now actuated from the ground wheels of such machine.

12 desifrnates the motor or engine which may be of any suitable form, size and construction.

13 isthe crank shaft of the en ine; 14, the fly wheel connected to the cra shaft; 15, 16, the coacting clutch members which normally connect the drive shaft to the driven shaft 17 of the transmission gearing and which is controlled in its operation by a foot pedal or other member in any well known manner, the member 15 being Vmounted on the engine shaft and the member 16 on the shaft 1'7.

The ower ytransmitting connections include t e driving shaft 17 which is con- -nected to the shiftable element or clutch 16, the shaft 18 journaled in the casing 1, the shaft 19 and worm thereon, change speed gearing 20 between the shafts 18 and 19, and motion transmitting 'means between the worm shaft 19 and the shaft 7.

This change speed gearing may be of any well known orm, size and construction and operable in any well known manner., it including gears 21 mounted upon the shaft 18 and gears 21a mounted upon a shaft which is parallel to the shaft 18. Some of these gears are shiftable in any well known mannerto vary the speed of the shaft 19.

The shaft 19 is here shown as provided with a worm 22 meshin with a worm gear associated with the driving element 5 of the differential gearing. It is also provided with an additional gear 23 meshing with a gear 24 mounted within the casing 1 on the. inner end of the shaft 7. As before stated, my invention is embodied in the Ford tractor and is adapted thereto by mounting the plate 9 on the rear of the casing 1 of the Ford tractor and substitutingl the shaft 19 havin means for mounting t e gear 23 thereon or the worm shaft now present in such tractors.

The speed ratio between the shaft 19 and the driven shaft 7 may be varied by changing the sizes of the gears 23, 24.

n operation, the tractor is connected to an agricultural machine to draw the same and at the same time the shaft 11 is coupled `at its rear end to the movable mechanism of the machine being drawn, 'said machine having suitable means for connecting and disconnecting at will the .shaft 11 from said mechanism. "'f

What I claim is: Y

A tractor comprising a driving axle including a differential gear ring, ground wheels mounted on the ends of the driving axle and supporting the latter, a power take o' shaft/arranged 1n rear of the wheel supported axle, a motor, power transmitting connections between the motor and said gear ring, and said power take olf shaftcomprising a shaft 19 having a gearmeshing with the gear ring and belng also connected to the power take o shaft and change speed gearing between the motor andy said shaft 19 differential.

In testimony whereof, I have hereunto` signed m name, at Syracuse, in the county o Onon a a, and State of New York, this 16th day o June, 1925. f

The speed ratio between the shaft 19 and the driven shaft 7 may be varied by changin the sizes of the gears 23, 24.

n operation, the tractor is connected to an agricultural machine to draw the same and at the same time the shaft 11 is coupled at its rear end to the movable mechanism of the machine being drawn, said machine having suitable means for connecting and disconnecting at will the .shaft 11 from said mechanism. "F

What I claim is:

A tractor comprising a driving axle including a differential gear ring, ground wheels mounted on the ends of the driving axle and supportinorr the latter, a power take off shaft arranged 1n rear of the Wheel supported axle, a motor, power transmitting connections between the motor and said gear ring, and said power take off shaft comprising a shaft 19 having a gearmeshingir with the gear ring` and being also connected to the power take off shaft and change speed gearing between the motor and said shaft 19 diiierential.

In testimony whereof, I have hereunto sifned mcy name, at Syracuse, in the county o Onon a a, and State of New York, this 16th day o June, 1925.
